Note the sudden drop in notebook CPU Performance

These two days, I suddenly found that my local performance was seriously degraded (because I work in a notebook, so it is very sensitive ). When I was very depressed, I began to check the settings ......

1. It was detected that ekrn.exe often occupies a very high CPU and thought it was a fault. The real-time protection of nod32..ekrn.exe is down, but everything is still...

2. Check power supply items. I found that no matter what I set, nothing has changed. (For power saving, there will be these settings in the notebook, when using the battery, the CPU frequency is reduced to a very low, my machine is the highest frequency of 30%)

3. Check whether the speedstep of the BIOS is enabled (this is the Inter technology, that is, the basis for implementing the above point). Everything is normal...

4. reinstall the system and install the driver... we are looking forward to a one-time test... that cup... (Even More sweaty, I was not allowed to upload images, saying that it was out of my maximum allowed range ....) dizzy ~~~

5. just as I was desperate, a meaningless operation saved me: restoring all the BIOS... restart, and suddenly the interface jumps out of a very cute warning (or for the first time I think this warning is cute ^_^): What did you forget, probably means: Your AC (DC) the power supply is not installed or cannot reach the specified power of 65w or ....

6. I changed an external power supply, and everything was normal... (although the score was not high, it took three years, but it was still cool ...)

It was always 30% before the solution was solved. Now we can go to 100%...

That happy, that excited, just like China suddenly entered communism ~~~

 

In the process of solving this problem, I also had more than N Baidu/GoogleArticleNo one has encountered such a problem. I would like to note that we can avoid detours for those who need it. (even if we reload the system for a loss, we may not just reinstall a few software. I am so sorry ~~)
